_Phil_. These distinctions of yours on the subject of obscurity I am disposed to think reasonable; and, unless the contrary should appear in the course of our conversations, I will concede them to be applicable to the case of Mr. Ricardo; his obscurity may be venial, or it may be inevitable, or even none at all (if you will have it so). But I cannot allow of the cases of Kant and Leibnitz as at all relevant to that before us. For, the obscurity complained of in metaphysics, etc., is inherent in the very _objects_ contemplated, and is independent of the particular mind contemplating, and exists in defiance of the utmost talents for diffusing light; whereas the objects about which Political Economy is concerned are acknowledged by all persons to be clear and simple enough, so that any obscurity which hangs over them, must arise from imperfections in the art of arranging and conveying ideas on the part of him who undertakes to teach it. _X_. This I admit: any obscurity which clouds Political Economy, unless where it arises from want of sufficient facts, must be subjective; whereas the main obscurity which besets metaphysics is objective; and such an obscurity is in the fullest sense inevitable. But this I did not overlook; for an objective obscurity it is in the power of any writer to aggravate by his own perplexities; and I alleged the cases of Kant and Leibnitz no further than as they were said to have done so; contending that, if Mr. Ricardo were at all liable to the same charge, he was entitled to the same apology; namely, that he is never obscure from any confusion of thought, but, on the contrary, from too keen a perception of the truth, which may have seduced him at times into too elliptic a development of his opinions, and made him impatient of the tardy and continuous steps which are best adapted to the purposes of the teacher. For the fact is, that the _laborers of the Mine_ (as I am accustomed to call them), or those who dig up the metal of truth, are seldom fitted to be also _laborers of the Mint_--that is, to work up the metal for current use. Besides which, it must not be forgotten that Mr. Ricardo did not propose to deliver an entire system of Political Economy, but only an investigation of such doctrines as had happened to be imperfectly or erroneously stated. On this account, much of his work is polemic; and presumes, therefore, in the reader an acquaintance with the writers whom he is opposing. Indeed, in every chapter there is an under reference, not to this or that author only, but to the whole current of modern opinions on the subject, which demands a learned reader who is already master of what is generally received for truth in Political Economy.
